This applet simulates the titration of a weak acid (in the beaker) with a strong base (in the burette). The pK of the acid is fixed. Base is added by pushing the stopcock button and the resulting pH is calculated and plotted. By finding the endpoint, we can determine the concentration of acid in the flask; we can also determine the pK of the acid by measuring the pH halfway to the endpoint.

This is a free, online textbook offered by Book Boon. 'Biofuels play significant roles in decarbonisation of our future energy needs and act to mitigate deleterious impacts of greenhouse gas emissions. Bioethanol - fermentation-derived fuel alcohol - is the world’s leading transportation biofuel and is currently produced from cereal and sugarcane feedstocks. However, the future lies with more sustainable fermentation substrates, including bio-wastes from agriculture and woody biomass. This book provides a timely overview of biomass-to-bioethanol conversion technologies and is aimed mainly at advanced students of biological and environmental sciences.'

This is a free course offered by the Saylor Foundation.'Bioorganic chemistry studies the chemistry of organic biomolecules. It is a rapidly growing interdisciplinary field that combines organic chemistry and biochemistry. Please recall that organic chemistry investigates all molecules that contain carbon and hydrogen, and biochemistry focuses on the network of molecular pathways in the cell. Bioorganic chemistry employs organic chemistry to explain how enzymes catalyze the reactions of metabolic pathways and why metabolites react the way they do. Bioorganic chemistry aims to expand organic-chemical research on structures, synthesis, and kinetics in a biological direction.This one-semester course will cover several advanced chemistry topics and will discuss the chemistry behind biological processes. The course begins by introducing you to the mechanisms behind the most common biological chemical reactions (Unit 1). You will then take a closer look at the metabolic processes of biomolecules. You will apply your knowledge of the structural features of organic molecules to biomolecules (Unit 2). The next four units will cover the chemistry of metabolic processes in the cell: lipid metabolism (Unit 3), carbohydrate metabolism (Unit 4), amino acid metabolism (Unit 5), and nucleotide metabolism (Unit 6). This course will also discuss the medical significance of the relevant deficiencies of these pathways.This course features a number of Khan Academy™ videos. Khan Academy™ has a library of over 3,000 videos covering a range of topics (math, physics, chemistry, finance, history and more), plus over 300 practice exercises. All Khan Academy™ materials are available for free at www.khanacademy.org.

Experiment is an online, crowdfunding, Open Science/Open Access platform for advancing the discovery, funding, and sharing of science, research, and innovative technologies. Experiment uses a Public Funding Model where backers funds go directly to the scientist/innovator/ researcher, so there is no middleman overhead involved (compared to 50-60% when receiving a grant at a university). Experiment is an all-or-nothing funding platform, meaning that the project much reach its target funding goal or no one's pledges are charged. Anyone can start an experiment project as long as the results are shared openly. All projects are rigorously reviewed, provided feedback, and scientifically approved by the Experiment Team.

This is an educational site about protein structure. While there is some brief explanations of DNA and protein, the most interesting sections of the site are on protein structure prediction and "Martin’s distinctly succinct guide to X-ray crystallography". The guide includes pictures of equipment and procedures along with the occasional short movie. There are also links to some of the structures produced by the Laboratory of Molecular Biophysics at the University of Oxford.
